武运粳7号是江苏的高产粳稻品种，因高感水稻条纹叶枯病而限制了其进一步的推广应用，因此改良其条纹叶枯病抗性具有重要意义。本研究是在前期利用分子标记辅助选择和农艺性状表型选择定向改良武运粳7号条纹叶枯病抗性的基础上，对14个改良系的重要品质性状进行比较分析。根据品质性状的综合表现，14个改良系中，C09、C11、C12和C13的多项品质性状优于武运粳7号，C14的食味值最高；C11、C12和C14不仅产量较高，品质也较好。
武運粳7號是江囌的高產粳稻品種，因高感水稻條紋葉枯病而限製瞭其進一步的推廣應用，因此改良其條紋葉枯病抗性具有重要意義。本研究是在前期利用分子標記輔助選擇和農藝性狀錶型選擇定嚮改良武運粳7號條紋葉枯病抗性的基礎上，對14箇改良繫的重要品質性狀進行比較分析。根據品質性狀的綜閤錶現，14箇改良繫中，C09、C11、C12和C13的多項品質性狀優于武運粳7號，C14的食味值最高；C11、C12和C14不僅產量較高，品質也較好。

Wuyunjing 7 is a japonica variety with high yield in Jiangsu province, but it is highly susceptible to rice stripe dis-ease ( RSD) , so that its further popularization and application are limited.Therefore, it is important to improve the RSD resistance of Wuyunjing 7.On the basis of directionally improving the RSD resistance of Wuyunjing 7 by molecular marker assisted selection and agronomic traits analysis in previous studies, we compared and analyzed the important quality traits of 14 improved lines from Wuyunjing 7.According to the comprehensive performance of quality traits of various lines, we found that C09, C11, C12 and C13 were better than Wuyunjing 7 in most quality traits.The taste value of C14 was the highest among 14 lines.As a result, C11, C12 and C14 have not only high yield but also excellent quality.
